Seo Master present to you: By Mike Marchak, Google Developer Team

Before looking back on this past year, we'd like to thank the developer community for your involvement and enthusiasm in 2008. Without you none of our accomplishments would've been possible and coming to work would not have been nearly as rewarding or exciting.



In 2008 the developer team at Google made it significantly easier for developers to build increasingly sophisticated web apps. Looking back, some of the most notable events from the last year include the App Engine launch, GWT 1.5 launch, Chrome launch, AJAX Language API launch, AJAX Libraries API launch and the broad adoption of OpenSocial.

We also worked hard to make it simple to integrate and extend Google applications through the launch of the You Tube API, Visualization API, Maps for Flash API, Finance API and Custom Search API.

We were also really happy to participate in the Open Handset Alliance where we saw the announcement of the Android Developer Challenge winners, the Android 1.0 SDK launch, and the first app downloads in the Android Market.

Our favorite part of 2008, however, was interacting with you at Google I/O and at Developer Days. These events allowed us to meet inspirational developers in 15 countries around the world who are building fantastic applications.

In 2009, we look forward to building products to make the web better and that let you, the developer community, build better apps on the web. We are already excited about seeing you at events next year.


Happy Holidays from the Google Developer Team.

Since Google Web Toolkit (GWT) launched, there have been many rich, robust Ajax applications which developers have told us they wouldn't have been able to build without GWT. We're thrilled to hear that GWT has increased productivity for developers and helped them to improve performance of their AJAX apps. On that note, we'd like to introduce you to 4 developers across a diverse range of web apps -- all of which were built with GWT. Whether you're new to GWT or not, these developers share some great insight into how they used GWT, what they like and would like to see from GWT, and finally their own learnings from building with GWT.

These developer videos, as well as descriptions of other GWT-built apps, are available here: Who's Using GWT. And if you're interested in the latest on GWT, check out the Official Google Web Toolkit Blog.

*Viewing tip: While we've embedded the videos here, we highly recommend watching them directly on YouTube and choosing the "watch in HD" option.

GoGrid is a cloud computing infrastructure service provider which enables you to deploy and scale load-balanced cloud server networks via a multi-server control panel. GoGrid was recently named Best In Show at LinuxWorld 2008. "We wanted to build a thick client inside the browser... GWT is very powerful and has increased our productivity greatly... We're able to build a very complex, rich, UI application quickly and easily." - Justin Kitagawa, GoGrid



Lombardi Blueprint is a business process mapping and diagramming tool. "We don't have to worry about all the browser quirks that you fight with when you're writing in pure javascript. We just write in the language that we like to use and they take care of all the difficult bits for us." - Alex Moffat, Lombardi Blueprint



scenechronize is a production management web application for film, television and commercials. "We chose to use GWT because it allowed us to write in Java which opened up a wide range of tools available for Java-based apps.... Because GWT supports multiple browsers, we're able to write our app so it looks and works the same across 4 major browser types." - Rob Powers, Scenechronize



Whirled is a social virtual world website which includes multi-player games. "We used GWT to build the social networking website part of Whirled, and it's done a lot of the heavy lifting for us... Whirled is now about 60K lines of code just for the client. Being able to enforce the same kind of engineering discipline that we do everywhere else has been a huge help." - Michael Bayne, Whirled

We're happy to announce the Google Visualization API Library for Google Web Toolkit (GWT). This has been a requested addition to GWT for some time now on the developer forum and we are excited to make it available.

You can now utilize the visualization and reporting capabilities of the Google Visualization API while writing native Java code for your GWT applications and enjoy the best of both worlds. The library includes wrappers for many of Google's visualizations, such as Bar Chart, Annotated Time Line, Map, Motion Chart, Organizational Chart and many others. We have marked all the visualizations that are currently supported by this library in the Visualization Gallery.

The library also includes classes that enable you to easily wrap any existing Visualization API-compliant visualization in GWT so that you can access it from Java complied by the GWT compiler. So if you want to wrap your own visualization or the nifty Piles of Money visualization, you can easily do so.

Lastly, the library includes a class that makes it easy to write new visualizations in GWT-compiled Java and make it available as JS for general use in the Visualization API. This is cool if you've been itching to contribute new visualizations but prefer coding in Java.

Here is example code that draws the well known Annotated Time Line chart in Java using the new Visualization API Library:

UPDATE: Changed the code font size to fit on one line so you can copy & paste

package com.blogpost.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.visualization.client.AjaxLoader;
import com.google.gwt.visualization.client.DataTable;
import com.google.gwt.visualization.client.Query;
import com.google.gwt.visualization.client.QueryResponse;
import com.google.gwt.visualization.client.Query.Callback;
import com.google.gwt.visualization.client.visualizations.AnnotatedTimeLine;


public class BlogPost implements EntryPoint {
  public void onModuleLoad() {
    AjaxLoader.loadVisualizationApi(new Runnable(){
      public void run() {
          Query query = 
                Query.create("http://spreadsheets.google.com/pub?key=pCQbetd-CptH5QNY89vLtAg");
          query.send(new Callback(){
           
            public void onResponse(QueryResponse response) {
              if (response.isError()) {
                Window.alert("An error occured: " + response.getDetailedMessage());
              }

              DataTable data = response.getDataTable();
              AnnotatedTimeLine.Options options = AnnotatedTimeLine.Options.create();
              options.setDisplayAnnotations(true);
              RootPanel.get().add(new AnnotatedTimeLine(data, options, "800px", "400px"));
            }
          });
      }}, AnnotatedTimeLine.PACKAGE);
  }
}

This code draws the same visualization that can be seen in the example for Annotated Time Line in the Visualization Gadget Gallery. Both get their data from Google Spreadsheets, only this code does so in Java instead of Javascript or as a Gadget.

Seo Master present to you: Tonight at a Google Campfire One we released Google Web Toolkit 2.0, aiming to do two main things for developers:

• Make it easier to build faster apps
• Speed up the overall development cycle

This is a very exciting release because it's the cumulation of a year and a half working with teams like Google Wave, AdWords, and Orkut (among many others inside and outside of Google) to evolve GWT to meet the needs of today's web applications. There are many features and improvements, but let me call out three which we're especially excited about.

Faster Apps

Introducing: Performance profiling with Speed Tracer
The first thing you'll notice in 2.0 is that we've added a new tool called Speed Tracer. Speed Tracer is a performance profiler for Google Chrome that allows developers to see what's going on in a way which hasn't been possible before. We've worked closely with the Webkit community to add instrumentation in the browser to enable developers to gain deep insights into how code behaves, uncovering problems which have been hidden up till now.

Introducing: Incremental app download with code splitting
Another feature we've added into Google Web Toolkit is developer-guided code splitting. Code splitting allows a developer to split up their application for much, much faster startup times. Imagine if you have a settings page that users go to once a week. Why download that JavaScript when the application starts up? With code splitting, your users download just the JavaScript they need to get started.

Faster Development

Introducing: Declarative UI with UiBinder
UiBinder is a new declarative UI framework in Google Web Toolkit which enables rapid design iteration and a clean separation between presentation layer and application logic.

Dive into the details and more features in GWT 2.0.

Seo Master present to you: Today we’re releasing videos from the Tech Talks and Fireside Chats at I/O 2010. A look back on each track:

Tech Talks:

From new programming languages to venture capital to 5-minute lightning talks, the Tech Talks track at I/O was a veritable potpourri of geeky goodness.

You can find videos and slides for the Tech Talks on the linked session titles below:

• Go programming - The Go programming language was released as an open source project in late 2009. Rob Pike and Russ Cox discussed how programming in Go differs from other languages.


• Opening up Closure Library - Closure Library is the open-source JavaScript library behind some of Google's big web apps like Gmail and Google Docs. Nathan Naze talked about the library, its design, and how to integrate it in with your setup.


• Optimize every bit of your site serving & web pages with Page Speed - Richard Rabbat and Bryan McQuade talked about Page Speed, an open-source Firefox/Firebug Add-on which allows web developers to evaluate and improve the performance of their web pages.


• SEO site advice from the experts - Matt Cutts, Greg Grothaus, Tiffany Lane, and Vanessa Fox offered SEO feedback on a number of actual websites submitted by the audience.


• Beyond design: Creating positive user experiences - John Zeratsky and Matt Shobe shared their tips on how to keep users coming back to your applications through a positive user experience.


• How to lose friends and alienate people: The joys of engineering leadership - Brian Fitzpatrick and Ben Collins-Sussman regaled the audience with tips on how to lead vs. manage.


• Ignite Google I/O - Brady Forrest and Ignite returned to I/O with an awesome line-up of speakers - Ben Huh, Matt Harding, Clay Johnson, Bradley Vickers, Aaron Koblin, Michael Van Riper, Anne Veling, and James Young.


• Technology, innovation, computer science, & more: A VC panel - This year was the first time that we had investors/VCs speaking at I/O. Albert Wenger, Chris Dixon, Dave McClure, Paul Graham, Brad Feld, and Dick Costolo (moderator) debated hot tech topics including betting on start-ups with non-technical founders and open vs closed platforms.
  

The Tech Talk videos are also available in this YouTube playlist.


Fireside Chats:

In the 9 fireside chats at I/O this year, Google teams were eager to talk about the latest ongoings with their respective product areas, as well as spend most of the time on audience Q&A.

This year, we decided to record fireside chats because we know how popular they are not just with I/O attendees, but everyone interested in hearing from the engineers behind our products. You can find videos for the fireside chats below:

• Android Team


• Android Handset Manufacturers


• App Engine Team


• Google Chrome Team


• Enterprise Team


• Geo Team


• GWT Team


• Social Web Team


• Google Wave Team

These videos can also be found in this Fireside Chats YouTube playlist or the YouTube playlist for each session track. (ex. the two Android Fireside Chats are also in the Android playlist)

On Monday, we’ll be posting the last batch of I/O videos from the Geo, Google APIs, and Google Wave tracks. Stay tuned!

Seo Master present to you: This year's Google I/O was one to remember, with demos and presentations that showcased the power of HTML5 for consumers and businesses, as well as a complete proliferation of Android apps and devices (some of which ended up in the hands of attendees).

Day one included a keynote presentation by our own Bruce Johnson and SpringSource's Ben Alex. Here they announced the Google and VMware partnership which makes it easy for developers to harness the power of Spring Roo and GWT to build rich enterprise web apps that are cloud portable. As part of this announcement, the GWT team released GWT 2.1 M1, which not only includes VMware integration, but also Data Presentation Widgets and an MVP Framework.

Along with the great keynotes, there were plenty of in-depth GWT sessions. In the event that you missed them, here's a recap:

• Measure in milliseconds redux: Meet Speed Tracer - Kelly Norton is back for round two to demonstrate what milliseconds of latency means to end-users, as well as how to identify the sources of latency within your app using Speed Tracer.
  
  
• Faster apps faster: Optimizing apps with the GWT Compiler - Have you ever wondered how you can speed up your GWT compiles? If so, follow along with Ray Cromwell as he delves into this topic, as well as other tips and tricks that you can use to streamline development with GWT.
  
  
• Architecting for performance with GWT - Last year we announced Google Wave, a cutting edge web app that introduces a new way of collaborating and communicating. This year Wave team lead Adam Shuck, and GWT UI guru Joel Webber share with everyone the optimizations both teams use when building GWT-based web apps.
  
  
• GWT Linkers target HTML5 Web Workers, Chrome Extensions, and more - GWT has some extremely interesting technology under the hood, and Matt Mastracci, CTO of dotspots, knows this as well as anyone else. For this year's I/O he provides an overview of GWT linkers, as well as how they created a one that turns a GWT module into an HTML5 Web Worker, and one that generates an HTML App Cache manifest automatically.
  
  
• GWT's UI overhaul: UiBinder, ClientBundle, and Layout Panels - GWT 2.0 shipped with some major UI enhancements that make it very easy to speed up your app, decrease load time, and control layout. In this session, Ray Ryan and Joel Webber show you how these new features interact with one another, and how you can use them to create the most optimal web app.
  
  
• GWT + HTML5 can do what?! If you missed the YouTube video of Quake II running in the browser, this session not only replays it, but goes into great detail as to how the three Googlers actually made it happen using HTML5 features such as WebGL and WebSockets.
  
  
• GWT testing best practices - In 2009, Ray Ryan gave a talk on how to architect a GWT app using the MVP design pattern. This year, Wave's Daniel Danilatos follows-up on Ray's talk, with a detailed overview of how to remove the pain of testing GWT apps using the MVP architecture.
  
  
• Architecting GWT applications for production at Google - If you haven't noticed, it's required that at least one of Ray's talks has the word "Architecting" in it. The good news is that his talks live up to their titles, and this session is no exception. Not only does Ray evolve the concepts discussed in his 2009, "Best Practices for Architecting GWT Apps", he dives into some of the upcoming GWT 2.1 features, and invites Ben Alex, from VMware, on stage to talk about the integration between Spring Roo and GWT.
  

In addition to the linked session titles where you'll find the videos and slides, you can also find all videos in this YouTube playlist for GWT I/O 2010 sessions.

It was fantastic meeting everyone out at I/O, and we hope that it was as exciting and educational for you as it was for us. As always, stay on top of the latest GWT 2.1 release progress on the GWT Blog, and be on the lookout for posts from other I/O tracks coming soon!

We look forward to seeing you there!2013, By: Seo Master

Seo Master present to you: I'm excited to announce new, highly requested features for App Engine which we unveiled a few minutes ago at Campfire One.

First, we're giving developers an 'early look' at Java™ language support for App Engine. The team has taken a standards based approach, implementing standard Java APIs on top of App Engine where possible. So instead of using the underlying App Engine datastore API, developers can program against Java Data Objects or Java Persistence API.

Developers will also be able to easily build AJAX web applications end-to-end in Java through integration with a new version of Google Web Toolkit and a Google Plugin for Eclipse to support the development experience.

In addition to the Java features, we've also released cron support , data import support, and secure access to data behind the firewall. To learn more, read the full announcement on the App Engine Blog and watch the videos from Campfire One below: (Note: The video will be live soon)



Still needing a developer fix? If you want to dive deeper into these new features, and how to get more out of App Engine and Google Web Toolkit, we encourage you to come talk to us at Google I/O on May 27-28 in San Francisco CA. We'll be there conducting in-depth App Engine and Google Web Toolkit technical sessions and talking to developers. We'd love to hear your feedback about the features, and just see what you are up to.

Seo Master present to you: Last Thursday was a momentous day for citizen participation in government. As you may have heard, President Obama hosted the first online Town Hall meeting with questions submitted and voted on via the internet. The Developer team at Google is honored that two of our technologies, App Engine and Google Web Toolkit, played a role in making this possible.

Google Moderator, built with App Engine and Google Web Toolkit, allows users to submit and vote on questions collaboratively. Originally developed for Google company meetings, it's now available for anyone to use -- but being featured on WhiteHouse.gov offered an unprecedented level of potential traffic and attention. We are thrilled that, thanks to scalable hosting provided by App Engine, Moderator successfully handled traffic from tens of thousands of simultaneous visitors.

During the 48-hour open voting period, the site peaked at 700 hits per second, and 92,934 people submitted 104,073 questions and cast 3,605,984 votes. In total, over one million unique visitors visited the site before the town hall. Even while the site was featured on major news outlets and even the Google homepage the other 50,000 apps built on App Engine were fully supported and experienced no adverse effects.

Since the front-end of Moderator was written using GWT, most user interaction with the site was handled via AJAX requests made from the browser to the server. This enabled a very responsive UI while at the same time keeping bandwidth down. It also made it easy to make some last-minute adjustments to the UI, while ensuring that the JavaScript was compatible with all browsers and all platforms.

As would be expected when a website is utilized by the White House and is featured in the media, there were dramatic, and sometimes unforeseen, upswings in traffic. The graph below shows some of the major surges in load to which App Engine adapted. Conventional web hosting strategies demand the pre-provisioning of enough servers to handle load. Sometimes, as was the case with Moderator on WhiteHouse.gov, accurate traffic estimates can be difficult to develop ahead of time. Fortunately, since Moderator runs on App Engine, all servers and resource allocation were handled automatically. With App Engine, you never need worry whether you've set up enough machines...we'll automatically spin up new servers as traffic grows.


If you haven't tried App Engine yet, we encourage you to join the 150,000 developers who have already built highly scalable web applications on top of Google's computing infrastructure. To learn more, visit code.google.com/appengine/ and make plans to attend our sessions at I/O at the end of May.
